If a standard set of wired speakers would work, it's possible to do wireless streaming through a TV.

With an HDMI equipped TV, a Chromecast (I'm sure Roku, Fire, Apple TV would work too), and a connected set of surround sound speakers hooked to the television, all your media can be streamed though the TV. I also have a set of Sony wireless headphones--plug those into the TV and stream music anywhere in the house.

Controlled with a smartphone, of course. It's a pretty cheap option, especially if you have an old set of speakers. Or really good TV audio (some are OK). Most people already have the television...

All that is possible but will require a lot of knowledge and a good bit of money to make it happen. There is so much you would have to learn and know before getting start. Certainly more than anyone could try and cover in a forum post. Start by learning how a Wi-Fi speaker works. Learn what hardware is needed to make it work and how the audio is streamed to the speaker. Good luck.
